quantum gateway
#13

Description

Neutron is a virtual network service for Openstack, and a part of
Netstack. Just like OpenStack Nova provides an API to dynamically
request and configure virtual servers, Neutron provides an API to
dynamically request and configure virtual networks. These networks
connect "interfaces" from other OpenStack services (e.g., virtual NICs
from Nova VMs). The Neutron API supports extensions to provide
advanced network capabilities (e.g., QoS, ACLs, network monitoring,
etc.)
.
This charm provides central Neutron networking services as part
of a Neutron based Openstack deployment

Multiple Floating Pools

If multiple floating pools are needed then an L3 agent (which corresponds to
a quantum-gateway for the sake of this charm) is needed for each one. Each
gateway needs to be deployed as a seperate service so that the external
network id can be set differently for each gateway e.g.

Instance MTU

When using Open vSwitch plugin with GRE tunnels default MTU of 1500 can cause
packet fragmentation due to GRE overhead. One solution is to increase the MTU on
physical hosts and network equipment. When this is not possible or practical thi
charm's instance-mtu option can be used to reduce instance MTU via DHCP.

(int)
Configure DHCP services to provide MTU configuration to instances
within the cloud. This is useful in deployments where its not
possible to increase MTU on switches and physical servers to
accomodate the packet overhead of using GRE tunnels.

(string)
Optional configuration to support how the L3 agent option
handle_internal_only_routers is configured.
all => Set to be true everywhere
none => Set to be false everywhere
leader => Set to be true on one node (the leader) and false everywhere
else.
Use leader and none when configuring multiple floating pools
